1. Trying to plug into European Power? Simple; Plug the shuko , Euro power cord into the Oconus plug, will only fit there. WARNING: Make sure
the two prong Euro/Shuko plug has the hot and neutral plugged in correctly with ground as your guide. If you do not, it can send 270 volts throught the
ups, and cause MPV to blow, which creates smoke, and UPS must be replaced.at your expense.
2. UPS will not turn on
.a. UPS test switch is off on front panel switch not pressed
1. a. Press front panel button to power up UPS.
TEST BUTTON
1 b. UPS's input circuit breaker is tripped, possible overload of UPS.b.
Unplug equipment to reduce load on UPS and reset (depress) circuit breaker. or replace fuse after consulting with electrician .
c. Poor connection of the power cord (mostly upon initial setup).c.
Make sure that the cord is firmly connected at both ends.
d. Problem with utility voltage: voltage is low, high, distorted or outlet is dead.d. Move UPS to a known properly functioning outlet to
test. Check outlet with multimeter or have a qualified electrician examine it.
2. UPS operates on battery even though normal voltage is thought to exist.a. UPS's input circuit breaker fuse in oconus is blown or input
circuit breaker on ups is blown.a. Unplug equipment to reduce load on UPS and reset (depress) circuit breaker.
b. Chronically high , low, or distorted line voltage.b. Test input voltage with UPS's bar graph by depressing and holding the test
button. If voltage is at fringes of transfer spectrum (i.e., for domestic UPSes, the defaults are at approximately 90V or 132V) the
UPS is in its hysteresis band and is waiting for the input voltage to move away from these transfer points before coming back on-line.
If the power quality is poor due to local cyclic heavy load switching or if unit is running off a generator, desensitize UPS by
switching option switch 1 to on position.
3. UPS frequently goes on to battery, more than once or twice an hour.a. Chronically high , low, or distorted line voltage.a. Set
Sensitivty option switch 1 and 2 to match input voltage range and desensitize
UPS. If the problem persists, contact a qualified electrician to
inspect power quality at outlet.
b. The power quality may be poor due to local cyclic heavy load switching (manufacturing environment, laser printers or photo
copiers on same circuit branch) or unit is running off a generator.b. Set option switch 1 and 2 to match input voltage range
and desensitize UPS. If the problem persists, contact a qualified electrician to inspect power quality at outlet.
4. UPS does not provide expected backup time.a. Batteries are not
fully charged.a. Recharge the batteries for 4 hours and retest.
b. Precalculated load on UPS does not equal actual load.b. Check UPS's output bar graph to check load on unit. Recalculate runtime of
UPS and compare to actual runtime. Remove unnecessary loads such as printers to increase runtime.
5. UPS goes to battery, gives high pitched signal , and shuts off.UPS is overloaded.Check UPS's output bar graph to check load on
unit. Remove unnecessary loads such as printers.
6. Replace Battery Light is illuminated and on-line light is extinguished. UPS is shut down and battery is discharged due to
extended power failure.Normal operation will return when power is restored and battery has charged sufficiently.
7. Replace battery light is illuminated and unit is on-line.Weak battery.Recharge the batteries for 8 hours and retest. If problem
persists after charging, the batteries should be replaced.
8. Site wiring light illuminated- UPS operates normally.Building
wiring error: UPS detected missing ground, hot-neutral polarity
reversal, or overloaded neutral circuit. Potential >5 volts between
neutral and ground possibly detected.Have electrician test utility
outlet and correct the building wiring.
10. UPS on-line making constant tone.UPS is overloaded.Check UPS's
output bar graph to check load on unit. Remove unnecessary loads
such as printers.
11. Indicators on front panel flash in a marquee fashion.UPS has
been shut down (put to sleep) by UPS monitoring software.UPS will
restart when AC power returns.
